Enhancing production with Electric Submersible Pumps (ESP) – Challenges and Solutions
ESP is a mature artificial lift technology having been in existence for at least 80 years. Yet its applications are still engineering intensive, and numerous challenges still remain. Two significant ones topping the list are run life and intervention cost. The run life of ESPs is still far from desirable. This is particularly true for fields with high H2S concentration. Most ESPs today are installed and replaced with workover rigs with jointed pipes. To replace a failed ESP, the waiting time for a workover rig can be long and the workover time and cost can be high, especially for offshore fields. This presentation first provides insights on the leading causes of ESP failures revealed through Dismantle Inspection Failure Analysis (DIFA) of hundreds failed ESPs. It then leads the audience through the research, development, trial tests of new technologies targeting 10-years of ESP run life and 1-day ESP replacement. It shows how subsea technology can be adopted to re-engineer the ESP power delivery system to bring about a whole new level of reliability. To move away from workover rig utilization, a novel rigless cable-deployed ESP system was developed. The presentation also highlights new techniques being developed to address other challenges such as slim well completion. Experience and technologies discussed in this presentation are applicable for operators worldwide. It is evident that when it comes to ESP challenges, operators cannot be passive. It is critical to actively engage and collaborate with service providers to turn challenges into opportunities.
